I still remember some guys saying here that EPYC is useless in HPC, despite more BW, seriously claiming that can be no viable use-cases that are memory bandwidth bound
I wonder why they disabled SMT on both Intel and AMD though
First, we are introducing HB-series VMs optimized for applications driven by memory bandwidth, such as fluid dynamics, explicit finite element analysis, and weather modeling. HB VMs feature 60 AMD EPYC 7551 processor cores, 4 GB of RAM per CPU core, and no hyperthreading. The AMD EPYC platform provides more than 260 GB/sec of memory bandwidth, which is 33 percent faster than x86 alternatives and 2.5x faster than what most HPC customers have in their datacenters today.
